Decomposable Cyclically Presented Groups and Shift Dynamics

Kirk McDermott*, Oregon State University
Talk Abstract: 
A group with a cyclically symmetric presentation admits an automorphism of finite order called the shift. In this talk we look at cyclically presented groups which admit a certain decomposition, and relate the shift dynamics for the group to the components of the decomposition. Topological methods are used to identify fixed points for powers of the shift.
